Application filed February 24, 1922. Serial 1T0. 538,927.

To all whom. it may concern:

Be it known that I, DELANEY ARKWRIGHT, Jr., a citizen of the UnitedStates, residing at Newton Falls, in the county of Trumbull and State ofOhio, have invented a new and useful Burner, of which the following is aspecification. v v

This invention relates to furnace attachments, and aims to provide novelmeans for directing air and powdered fuel to the burner of a furnace inproper proportions to facilitate the burning thereof.

Another object of the invention is to provide means for adjusting thefuel supplying nozzles with respect to each other to insure the fuelbeing properly mixed with the air entering the furnace.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides inthe combination andarrangement of parts and in the details of constructionhereinafterdescribed and claimed, it being understood that changes in the preciseembodiment .of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawing: Figure 1 is a side elevational view of theattachment disclosing the same as connected with the fuel intake openingof a furnace.

Figure 2 is an end elevational view of the attachment.

Figure 3 is a sectional view through the attachment.

Referring to the drawing in detail, the

reference character 5 designates a laterally extending pipe formedintegral with the furnace casing, which pipe provides the fuel feedingopening to the furnace.

The attachment comprises a body portion 6 formed with. a circumferentialflange 7 adapted to abut the flange 8 formed on the pipe 5, where theflanges may be secured as by means of the bolts 9.

The outer end of the body portion 6 is formed with cut out portions 10to permit air to passinto the body portion, suitable means beingprovided for controlling the passage of air through the openings 10. .Asshown, a pivoted member 11 is provided which pivoted member has portionsoverly in the openings. 10 and cut off the air entermg-the body portion6, should it be de sired to reduce the quantity of air passing into thebody portion 6. v

"Pipes 12 are formed. integral with-the body portion 6 and extend atangles with respect to the side walls of the body portion, the outer orfree ends of the pipes 12 terminating at points in the same plane withthe front end of the body portion 6. Adjustably supported within thepipes 12 are the pipes 13, which pipes are formed with flanges 14, bymeans of which the pipesmay be connected with a suitable blast of airfor feeding powdered coal into the body'portion 6.

Thus it will be seen that by moving the in pipes 13 within the pipes12,'the inner ends of the pipes 13 will be moved towards and away fromeach other to accomplish the adjusting result. It might also be statedthat" passing from the opposite pipe causing the powdered coal to bethoroughly mixed with the air passing throughthe openings 10.

A pipe 15 extends from the body portion 6 and provides means forsecuring the supply pipe 16 to the body portion, the supply plpe 16providing mea-nsfo'r directing a blast to the body portion or mixingchamber 6' for preheating the mixing chamber and facilitating thestarting of the burning 'op- I eration.

.Pipes l7'also communicate with the pipes 13 and supply a blast tothepipes 13 to'preheat the pipes and aid inthe burning of the fuel.

In the use of the device, a blast directed" throughpipe'16 and into thebody portion or mixing chamber 6, where the same causes the mixingchamber 6 to become heated.

l Vhen the mixing chamber becomes heated to the proper degree, the blastthrough the pipe 16 is cut off and powdered coal is admitted to thepipes 13, the pipes 13 being Y however properly adjusted to cause theproper mixing of the powdered coal and air. f Having thus described theinvention, what is claimed as new is In combination with a furnace, abody portion in communicatlon with the furnace,

a fuel supply pipein communication with the bodyportion, pipes extendingat an les with respect to the body portion and'having their outer endsdisposed in a plane beyond In testimony that I claim the foregoing asone end of the body portion, angularly dismy own, I have hereto aflixedmy signature posed. air delivering pipes positioned in the in thepresence, of t-Wowitnesses,

first mentioned pipes and adjustable longi- 5 tudinally thereof, andhaving their deliver- DELANEY ARICWRIGHTi ing ends dis-posed towardseach other, and Witnesses: terminating at points in spaced relation J.'W'. HUMES,
